INTERNET OF THINGS-BASED INTELLIGENT LIGHTING CONTROL SYSTEM AND CONTROL METHOD THEREFOR

Provided are an Internet of Things-based intelligent lighting control system and a control method therefor, the system comprising: an infrared sensing module, a photosensitive sensing module, a PWN brightness regulating module, a delay triggering module, and a ballast module. By means of a radiant heat effect of an infrared sensor H1, the infrared sensing module senses heat radiation within a detection range to enable an infrared receiver U6 to receive temperature changes. The photosensitive sensing module converts an optical signal into an output electric signal by using a photoresistor, and automatically adjusts indoor lighting according to the brightness of natural light. A variable resistor RV5 in the PWN brightness regulating module is connected in series in a circuit so as to adjust an output voltage value by means of changing a resistance value. The delay triggering module receives the sensing conduction voltage of the infrared sensing module and the photosensitive sensing module, and intelligently con
